Frequently Asked Questions - SN74AHCT126N TEXAS INSTRUMENTS
What is the SN74AHCT126N used for?
The SN74AHCT126N is a quad buffer gate with 3-state outputs. It is used to buffer digital signals, boost drive strength, and isolate logic sections in digital circuits.
What is the supply voltage range for the SN74AHCT126N?
The device operates with a supply voltage between 4.5 V and 5.5 V DC, making it compatible with standard 5V logic systems.
How many independent buffers are inside the SN74AHCT126N?
It contains 4 independent buffer gates, each with a separate input, output, and output enable pin. This allows flexible use in various configurations.
What does 3-state output mean?
3-state outputs can be in one of three states: HIGH, LOW, or high-impedance (Z). When the output enable input is inactive, the output becomes high-impedance, effectively disconnecting it from the bus.
What is the package type of the SN74AHCT126N?
The 'N' suffix indicates a 14-pin DIP (Dual Inline Package), which is through-hole mounted and suitable for breadboards or PCBs.
Can the SN74AHCT126N be used for level shifting?
Yes, with a 5V supply, it can accept TTL-compatible inputs and provide CMOS-level outputs. However, it does not shift to lower voltages; it is primarily for 5V systems.
What is the maximum output current?
Each output can source or sink up to 8 mA at full voltage swing. For higher current, a buffer or driver with more output capability would be needed.
What are the operating temperature limits?
The recommended operating temperature range is -40°C to +85°C, making it suitable for industrial applications.
How should I handle the SN74AHCT126N to avoid damage?
Handle the IC with proper ESD precautions such as using an anti-static wrist strap and mat. Avoid touching the pins directly and store in anti-static packaging.
Is the SN74AHCT126N RoHS compliant?
Yes, Texas Instruments produces this component as RoHS compliant and lead-free, conforming to environmental standards.
